Microscopy and Spectroscopy on Model Catalysts in Gas Environments
In surface science there is great effort to move from studying simple, flat model surfaces in vacuum to investigating more complex model catalysts in gas environments (in situ). This thesis gives three examples of such studies using microscopy and spectroscopy.

Towards a mechanistic understanding of nanoparticle behavior using zebrafish
The work described in this dissertation contributes to a better mechanistic understanding of nanoparticles in vivo. To achieve that goal, we used the zebrafish as a highly predictive pre-screening model of nanoparticles.

Daphne Wouts doet bijzondere ontdekking over boekenlijst Librije Enkhuizen
Boek- en kunsthistorica en promovenda Daphne Wouts heeft een bijzondere ontdekking gedaan. In het Westfries Archief in Hoorn vond ze op drie oude stukken papier twee boekenlijsten van de Enkhuizer Librije uit 1634 en 1649. Het Noordhollands Dagblad schreef een artikel over haar bijzondere ontdekking…

Resolving the building blocks of galaxies in space and time
We investigate the buildup of galaxies from various vantage points. The first two chapters focus on the stellar content of galaxies, especially the distribution of stellar masses at birth and potential variations therein in various galactic environments.

Evolution of Molecular Resistance to Snake Venom α-Neurotoxins in Vertebrates
We have examined sequences from the ligand-binding domain of the nicotinic acetyl choline receptor (nAChR) in 148 vertebrate species. We are in interested in this receptor because the α-neurotoxins of many venomous snakes binds to this receptor in its location at the neuromuscular junction in all ve…

Betere blik op synthetische brandstofproductie
Synthetische brandstof is schoner dan natuurlijke olie, maar het productieproces is nog niet efficiënt genoeg. Nu hebben wetenschappers voor het eerst direct de moleculen waargenomen die uit het chemische proces ontstaan. Het opent de deur richting efficiënte ‘designer’ katalysatoren. Publicatie op…
